IMPROVEMENT IN SELVF-OILING SPlNDLE-BOLSTE-R FOR SPINNING-FRAMES.

Specification forming part of Letters Iatent Na 44,988, dated November 8, 1864.

To all whom it may concern Be it known that I, ERAsTUs N. STEERE, of Providence, in the county of Providence and State ot' Rhode Island, have invented a new and useful Improvement in Oiling Spindles of Spinning-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specitication, in which- Figure 1 is a transverse section of a number ot' spindle-bolsters in the rail of a spinning-machine. Fig. 2 is a plan of the same. Fig. 3 is a transverse section bythe line A A of Fig. 2. Fig. 4 is a transverse section of a bolster and rail as employed in mules Similar letters of reference indicate correspending parts in all the figures.

In Letters Patent No. 34,221, granted to me, the said ERAsrUs N. STEERE, under date of January 21,1862, a description is given of an improved spindle-bolster, in which the improvement claimed consists in a combination ot' an isolated absorbent and suitable passages or conductors, in connection with the ordina-ry I bcarin g ot'aspindle-bolster, bymeans of which a supply of the lubricating-liquid was held in reserve by the said absorbent in a surrounding chamber, from which it was dra-wn as it was required by the revolving ot' the spindle.

The invention in this instance consists in an improved construction and arrangement ot' such bolster, and in connection therewith a distributing channel and reservoir, by means of which a number of spindles may be sup plied with oil at the same time without the necessity of oiling each spindle separately.

To enable others skilled in the art to make d use my invention, I will proceed to deribe the same.

ln Figs.land2of the drawings,G D E G represent substantially my improved bolster, above referred to as patented January 2l, 1862. Instead, however, of shell h, I cup-out the rail B, as shown in Figs. 1, 3, and 4, to form the annular chamber for the reception of the isolated absorbent S, and I form the inner shell, f f, with a ange or cap, fi, to cover the annular chamber either wholly, as shown in G D E, or partially, as in G, for the purpose of excluding dust and other foreign matter, and to keep the absorbent in its place, the former being preferred as most effectual 5 and I provide this inner shell, f, with a nut, m, screwing upon the lower end, as shown, to draw it down into the rail B, anda washer, t, of soft metal, as apacking to form a joint with the shoulder on the inner shell at the bottom of the annular chamber. e e are the passages through which the lubricatingfluid is drawn from the annular chamber to the spindle-bearin g, the same being formed in E by cutting a slot, e', in top of the shell, as shown.

In the bolster of mule-spindles, Fig. 4, the nut m and washer t may be dispensed with and-the inner shell made to fit so snugly in the rail B as to form a tight joint in the bottom ot' the annular chamber, the nut and washer being only necessary in the bolster of spinning-frames to provide for the setting of the spindles after the said frame is otherwise complete.

It will be seen that by simply clipping out77 the rail, as shown and above described, the separate exterior shell heretofore l employed is entirely dispensed with, thereby saving both the material and labor required in its construction, besides greatly simplifying my improved bolster. Moreover, by cupping out the rail in this mannerI am enabled to employ an additional improvement-viz., The distributing channel or reservoir H, Figs, 2 and 3, extending the entire length of the rail in front of the bolster, and connecting with the annular chambers thereofby passa ges a a. This channel may be covered, as it should be, to exclude dirt, by forming it somewhat wider at the top and with a dovetailed lip upon each side, as shown in Fig. 3, for the reception of a strip of sheet-lead or other soft metal, which is secured therein by hammering, and is afterward trimmed or smoothed down evenly with the surface of the rail by a butt-wheel, or otherwise. rIhe lubricatingilquid is supplied to this channel by means ot' two or more cups or openings formed therein like g, Fig. 2. Generally in an ordinary-sized spinning-frame one such cup may be formed in each end of the railB and one other midway between the ends, and when this channel is once iilled it will distribute a constant supply ot' oil equally to each spindle. It will keep the oil clear and limpid, and will prevent the waste which occurs from frequent and careless oiling at each spindle. It is obvious that this channel is equally applicable to the step or lower bearing of a spindle, orY to the bolster or upper bearing, and. it is my intelltion to use the same in both connections.

I do not claim a screw upon the lower part of a bolster and a nut for drawing it down so as to close .the joint between the bolster and the bottom of the oil cup neither do I cla-im the use ota washer to close the joint more perfectly; but,

Having described my invention, what I claim, and desire to secure by Letters Patent, iS-

1. The annular chamber formed by cupping out the rail, in combination with thc bearing of a spindle-bolster, substantially as described 2. In combination with an annular chamber surrounding the bearing of a spindle-bolster, as described, a suitable flange or cap, '5, as a cover for the same, substantially as described, for the purpose set forth.

3. 'Ihe channel or reservoir H, in combina tion with a spindle-bearing, substantially as described, for the purpose specied.
